The scientists admit the first 400 years of the cup’s history remain a mystery, and they can’t prove the chalice ever actually touched Christ’s lips.

But they insist there is no doubt that this is the cup that early Christians revered as the chalice used at the Last Supper.
“The only chalice that could be considered the chalice of Christ is that which made the journey to Cairo and then from Cairo to León — and that is this chalice,” said Torres, who teaches medieval history at the University of León.
